Hello, I have a network 192.168.25.0 and I need specify the following rules: 192.168.24.1 to 192.168.25.33 -> just should have HTTP access. 192.168.24.34 to 192.168.25.133 -> just should have FTP access. 192.168.24.134 to 192.168.25.254 -> just SSH access. I could do it using a loop for and creatiang one rule each time for each ip address. But I think this is not a best solution. I tried using: iptables -A FORWARD -p tcp -s 192.168.25.1-33 ... but was not successful. Is there any way to make this works ? Thanks!
